Loading limits For plasma welding, the values for the plasma gas flow rate and maximum welding cur-
dependent on the rent must lie within the set limit values. An upper or lower exceed of these limit values
plasma gas flow can change the plasma properties, e.g.:
rate -
-
NOTE!
Do not exceed the lower limit values set for plasma gas values and max. welding
current during operation.
NOTE!
The minimum coolant flow rate is 1 l/min
